Quick recap
Two years after Lane's capture, what's left of the Syndicate has become the Apostles, terrorists for hire working for an extremist called John Lark. In Berlin, Ethan chooses to save Luther and loses three plutonium cores. The CIA forces agent August Walker onto the team. In Paris, Ethan poses as Lark for the broker known as the White Widow and, in exchange for one core, helps break Lane out of a police convoy. Ilsa resurfaces with orders to kill Lane. In London, the team exposes Walker as Lark, and he kills Hunley. It all ends in Kashmir, where Lane plans to set off two bombs and contaminate the water of a third of the world. Julia, Ethan's ex-wife, works there. Ethan brings Walker down in a helicopter duel, the bombs are defused, and Lane goes back to MI6 custody.
